Ford's calling it the "world's most efficient mid-size sedan" to be safe, but given it looks and performs just like a regular vehicle it can safely be called the world's most efficient car... any current car buyer could operate as their sole vehicle.

We'll see the car in person later today during the opening day of the Detroit Auto Show and will bring you more information then.
